Hello doc,

I recently on febuary 1st engaged in unprotected sexual activity with a girl whom claims to be un infected... However since that experience I have noticed some changes in my body... I am a big person about 240lbs I do not know if this makes a difference on detectable antibodies or not, but I have had three antibody tests 10, 12, and 14 weeks post exposure... So this gave me a sense of relief but I keep reading about the 6 month deal... I also have been a member on med help, I told them my story and in the "expert forum" I contacted a doctor by the name of Edward W. Hook whom said I was perfectly fine and had nothing to worry about... So this made me feel a little better because I have been stressing over this to the point of not eating and not sleeping... They also claim that a group of 300 hiv experts have never seen a 6 week negative antibody test become positive later??? I am no specialist so I am asking what any Doctors here think of this???

As for the mosquito bites headline... I was curious about a mosquito bite I got yesterday because it swelled up tremendously... The mosquito bit me on the left arm and I slapped it pretty hard to kill it... within 5 minutes there was a huge welt (about 1in. in diameter) which then turned into a a puffy welt that was about 3-4 inches in diameter and raised... I was working out at the time, and within an hour or so the swelling went away, and left a hard itchy lump (typical mosquito bite).

1. I was curious to know if that swelling could be an indication of hiv infection, or any viral infection?
2. What could trigger such a drastic response?
3. Do you feel I am in the clear or do you think I need additional testing?
4. Have you ever seen anyone seroconvert after a 3 month negative antibody test?
